The managing director, chief financial officer and chief operating officer of US Highland were killed in a plane crash Saturday night. Mats Malmberg (pictured), Damian Riddoch and Chase Bales were three of five partners in the Oklahoma-based motorcycle manufacturer. Highland was founded by Malmberg in Sweden, but the company moved its manufacturing base to Oklahoma only recently.

The small plane was piloted by Bales and the three men were the only killed when it crashed en route to Tulsa International Airport around 10 PM. Reports indicate that Bales radioed that he was low on fuel shortly before the crash.
